Kimber sells a boatload of 1911s every year and the do put out quite a few dogs but when the run right they are a decent 1911. I'm not big on the fact that the $1400 ones have the same marginal quality internal parts as the $800 ones. I've owned two with internal extractors and they both ran very well but I only use top quality mags.
The external extractor models were such a flop that the switched back to internal and even started swapping slides on pistols sent in for service. The external extractor is a great concept in my opinion but they just couldn't get it right. Kimbers customer service down right sucks so if you have problems I wouldn't send it back to them.
Here is a Raptor with external.
